Abstract: | The half-sandwich type compounds C5H5RhP(OR)3]2 (R = CH3, C2H5, C6H5, p-CH3C6H4, p-ClC6H4) have been prepared from (P(OR)3)2RhCl]2 and NaC5H5. The NMR. data as well as the IR. and mass spectra of the new compounds will be discussed. The preparation of C5H5Rh(CO)P(OC2H5)3 is also reported. |
